Read Sonar Festival's statement:
"For 25 years Sónar has been scanning the planet for the most advanced music on Earth. Now the festival turns its antennas upwards, sending music into space in an attempt to make first contact with an alien civilization."
They have been celebrating, apparently, by sending music to aliens. It’s part of a joint project with METI International.
